Denver, CO (Sports Network) - Tim Duncan posted 18 points and 10 rebounds, as San Antonio moved up a notch in the Western Conference playoff standings with a 104-85 win over the Denver Nuggets.

Manu Ginobili and Richard Jefferson each tallied 15 points for the Spurs, who sit seventh in the West, a half-game ahead of Portland and a half-game behind Oklahoma City.

Tony Parker and DeJuan Blair both scored 12 as San Antonio snapped a two-game skid.

Chauncey Billups scored 27, but the Nuggets lost on the night they got back forward Kenyon Martin. Carmelo Anthony had 19 points before being ejected midway through the fourth quarter for Denver, which is tied with Utah atop the Northwest Division with two games remaining for each team. Denver shot just 39.2 percent and had a four-game winning streak broken.

Martin, who missed the previous 18 games with a left knee injury, had six points and 10 rebounds in 22 1/2 minutes of court time.

Denver will now likely finish either third or fourth in the West. Dallas won its game at Sacramento Saturday and is one game ahead of the Nuggets for second place in the conference.

Anthony's layup brought the Nuggets within 68-63 just 70 seconds into the fourth quarter, but the Spurs then put the game away by scoring the ensuing 13 points. Blair's layup capped the burst and the Spurs were never challenged down the stretch.

"We got into the bonus with nine minutes left and were able to attack the basket a little more," Duncan said. "I think DeJuan did a great job of getting into the middle and making some great passes. Manu hit some shots, so I think it was good ball movement, make some and it gave us breathing room."

San Antonio held a 20-19 lead after one quarter and a 45-40 edge at the half. The Spurs were up as many as 11 in the third period.

The Nuggets were called for fourth technical fouls in the final quarter. Anthony was ejected for arguing with officials.

"We got frustrated. There are a lot of equations that factored in to that," Martin said. "We have to keep our head up and be professional. Things happen, that is sports. Frustration creeps in in many different ways."
